One of the first things I did personally was swap out the mag and slide release controls with extended Tactical versions. With just a little more grip space, that might not have been necessary. The Glock 43X is the remedy to that issue for a lot of Glock lovers who were awaiting that slim micro-compact.
Ideal for CCW
Will take a beating and perform when you need it to
Slimline frame helps reduce printing if carrying concealed
Increased capacity, up to 10 rounds, due to a longer grip than the G43
The longer grip doesn't conceal as well as the standard Glock 43
The subcompact grip is something people have gotten used to, but now the pistol takes a single stack magazine, which means the width of the grip is almost cut in half. That's a big change to get used to. The 9mm round seemed to feel more snappy coming from the G43. If only the grip was long enough to wrap all of my fingers around...
In comes the Glock 43X. Instead of 6 rounds, you now get a 10 round capacity, meaning a longer handle. For me, that translates into a positive grip immediately from the draw. I can get on target faster, cutting grip adjustment time. And even better, I can wrap my hand around the grip to have a better follow-up shot control.

The barrel length didn't change, still less than 3.5" overall, so the carry options don't change if you previously carried the G43. The only difference that really meant anything to me personally is that there is more of a handle to conceal if you're carrying as a CCW. Wear a looser shirt, or get comfortable with appendix carry.
The performance overall is what you would expect. You're not going to go for longer shots with a sub-compact. This gun is for self-defense and concealability. The max range you would need to reach out to, realistically, is around 25 yards. Most encounters requiring you to defend yourself are typically going to be up close and personal, so effective range isn't really a thing in those circumstances.
That's pretty much the short and simple of what I think about the Glock 43X. If you've had any issues, or just have something to add, let us know.
Until next time, keep shooting!
